CROSS REFERENCE TO RELATED APPLICATIONS
This application is a continuation application of international patent application PCT/EP2011/069214, filed Nov. 2, 2011, designating the United States and claiming priority from German application 10 2010 061 271.5, filed Dec. 15, 2010, and the entire content of both applications is incorporated herein by reference.
FIELD OF THE INVENTION
The invention relates to a heatable connection apparatus including media-conducting, electrically heatable hoses. The connection apparatus includes a junction piece which has two connection nipples for respective hose ends and has a further connection communicating with the conduit interior. Each hose is provided with two electrical heating conductors embedded in the hose at least over part of the length of the hose. The ends of the heating conductors are routed out of the hose in order to form a connection with an electrical component.
BACKGROUND OF THE INVENTION
A wide variety of electrically heatable hoses for use in motor vehicles are known. The medium flowing between two connection points in these hoses is heated by these hoses.
A heatable hose having at least one electrical heating conductor which serves to heat a medium flowing in the hose is known, for example, from DE 102 01 920 A1, wherein the heating conductor extends over at least part of the length of the hose and is composed of a metal core and a sheath.
The heating conductor is usually embedded in a layer of the hose. In a multi-layer hose, the heating conductor can also be arranged between two layers. The ends of the heating conductor are exposed in order to be able to connect them to a voltage source which is required for operating the heating conductor. The exposed ends of the heating conductor are usually arranged at one end of the hose. However, it is also possible for an exposed end of the heating conductor to be arranged at each end of the hose.
The exposed ends of the heating conductor are provided with an electrical connection (plug) and are then connected to a voltage source. Since the voltage source is usually not arranged directly at the hose, the exposed ends of the heating conductor have to have a predefined length in order to form a connection to the voltage source via the plug.
The heatable hose line preferably has two helical heating conductors which are supplied with power at one end and are short-circuited at the other end. This ensures that the line is heated.
EP 1 329 660 B1 discloses a flexible multi-layer heatable hose having at least one reinforcement layer and an elastomeric outer layer as well as an electrical heating conductor which is used for heating a medium flowing in the hose. The heating conductor extends over at least part of the length of the hose and is composed of a metal core and a sheath, wherein the heating conductor is embedded outside the outer stratum of the reinforcement layer but under or within the elastomeric outer layer. In order to permit simple and reliable electrical contact to be made between the heating conductor and a voltage source, the elastomeric outer layer is less strong than the heating conductor and is dimensioned such that the heating conductor can be exposed by means of a radially outwardly acting force by cutting through the original or weakened elastomeric outer layer, but without damaging its metal core and its sheath, and can be connected directly to an electrical connection. The heating conductor preferably runs beneath or within the elastomeric outer layer in a helical manner at least over part of the length of the hose.
The described technology of the heatable hoses has been proven to be useful when transporting liquid media between two connection points or connection nipples of motor vehicle assemblies, for example storage tank, injection unit, pump et cetera. However, in particular applications, it has been found that the liquid medium can freeze in the hose connection nipples of the connecting blocks which are usually in the form of standardized plug connections, in particular quick-action plug connectors, and are arranged at the ends of the hose.
This risk of freezing occurs particularly in exhaust-gas after treatment systems for reducing nitrogen oxide emissions from an internal combustion engine. In this case, nitrogen oxide is converted into atmospheric nitrogen and water vapor with the aid of selective catalytic reduction technology (SCR). The reducing agent used is an aqueous urea solution which is carried along in a separate storage container. The aqueous urea solution is fed out of the storage container by means of a delivery module or a pump and is supplied to a metering module, from which the urea solution is injected in a metered manner into the exhaust-gas flow upstream of the catalytic converter. Excess reducing agent is conducted from the delivery module back into the storage container via a return line.
Hose lines for conveying the reducing agent are provided between the storage container, the delivery module and the metering module. These hose lines have to be connected to said assemblies in order to establish the fluid connection.
For the hose connections to the assemblies, it is possible to insert the quick-action plug connectors, which are standardized in the automobile industry, at the hose ends, the receptacle parts of these hose ends being mounted on the assemblies ex-factory. The quick-action plug connectors (quick connectors) have the advantage of rapid mounting of the hose and a wide variety of embodiments of the quick-action plug connectors are known. They are most frequently designed as a “male part” on the assemblies and as a “female part” on the hose ends, the latter having a connection nipple for the hose end, onto which the end of the hose which is to be connected is pushed and fastened such that it is media-tight.
The hose lines between the reservoir container and the exhaust gas line have to be capable of being heated, since below −11° C. there is a risk of the aqueous urea solution freezing. It is known to avert the risk of freezing by using the known, electrically heatable hoses. Although these electrically heatable hoses have been proven to be useful, in extreme applications the plug connectors are the weak point of the exhaust-gas treatment systems in respect of the risk of freezing. There is still a risk of freezing in the plug connections themselves.
In order to provide an apparatus which protects against freezing of the aqueous urea solution even in the connections of the hose lines to the assemblies which are to be connected, it has already been proposed to use connecting blocks which can be heated by cooling water for the hose connections. These connecting blocks are designed in such a way that the cooling water, of which the temperature can be controlled, is flushed through them. As a result, both the hoses and the plug connectors can be thawed.
The use of special quick-action plug connectors (quick connectors) which have a separate electrical heating element (for example a heatable ceramic component) is also known. This has the disadvantage of being a very expensive and complex solution which also requires an additional electrical connection (plug).
In order to measure the concentration of urea in the solution during the injection process, a sensor is inserted into the pipe or hose line via a junction piece (T piece, Y piece), wherein the hose line has to be disconnected. The region of the junction piece is also subject to the risk of freezing. This region of the hose line should therefore be electrically heated too. However, no heatable designs are known for these junction pieces at present because two hose ends meet at a disconnection interface.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a connection apparatus in which the entire line branch, that is to say the hose and the connection points of the hose and the assemblies which are to be connected, can be continuously and directly heated and which is distinguished by a cost-effective solution with a low level of technical complexity.
In the region of the junction piece, the two heating conductors are routed from each hose line end and each of the two heating conductors is crimp-connected to corresponding ones of the heating conductors of the other hose end, with the result that there is an electrical continuity and the current can flow. There are therefore two crimped heating conductor pairs, one on each side of the housing.
Each heating conductor pair is bent downward in a pressed together manner and by way of the crimp point is routed first from above beneath a lateral bridge bracket of the housing of the junction piece downward in the direction of the housing base, from where it is deflected through 90° and placed around the base of the junction piece in close contact with the housing. On the corresponding opposite side, each heating conductor pair is routed upward again and, by way of the dedicated crimp location, is first passed from below through the bridge bracket, which forms a kind of locking bar, of the housing and is therefore positioned in this location.
Therefore, each crimped heating conductor pair is bent downward and deflected through 90° around the base of the junction piece and routed upward again on the opposite side. This arrangement, which includes the junction piece, ensures that enough electrical heating power is provided to ensure that the aqueous urea solution does not freeze in the region of the junction piece and, in the event of the aqueous solution freezing, it can thaw in the region of the junction piece.
In an advantageous embodiment of the invention, the two bridge brackets are arranged opposite one another on the outside of the housing and each bridges an axial channel. The axial channels are machined into the surface of the cylindrical housing of the junction piece. The crimped heating conductors are placed and thus routed in the channels or grooves.
In a further advantageous embodiment of the invention, the heating conductor pairs are placed and routed in the channels, one arriving from above, and one arriving from below the housing base.
In a further advantageous embodiment of the invention, the junction piece, which is assembled with the heating conductor pairs, is encapsulated with a plastics material. The structure is protected from external influences as a result.
In a further advantageous embodiment of the invention, the potting layer of the plastics material is composed of polyurethane or polyamide.
By virtue of the junction piece, which can be heated in this way, the entire conduit branch of the urea solution from the storage container up to the exhaust-gas line can be heated continuously and directly. There is no longer a cold bridge or blockage within the conduit branch. It is no longer possible for the junction piece to freeze. The heating conductors from the existing hose line which are already present are used for heating the junction piece. There is no longer any need for an additional electrical connection for heating the junction piece.

 DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
The junction piece 11 shown in FIGS. 1 to 4 has two diametrically opposite connecting nipples (12, 13), onto each of which the respective ends of electrically heatable hoses (14, 15) are pushed. The hose ends 14 and 15 are fixed on the respective ones of the hose connecting nipples (12, 13) by corresponding press sleeves (16, 17).
The junction piece 11 has an internal threaded connection 18 for the sensor (not shown) which, as a mating piece, has an external threaded connection which was already fitted ex-factory and is mounted by a simple threaded engagement.
The two hoses (14, 15), which are shown only by way of their corresponding short end sections, are heated by respective sets of heating conductors (21, 22) and (23, 24), often also referred to as heating wires, which are integrated in the respective hose structures. In order to connect the heating conductors (21, 22) of one hose end (hose 14) to the heating conductors (23, 24) of the other hose end (hose 15), the individual heating conductor sets (21, 22) and (23, 24) are stripped at the corresponding ends of the hoses (14, 15).
The free stripped end of the heating conductor 21 of one hose end (hose 14) is crimped to the free stripped end of the heating conductor 23 of the other hose end (hose 15) via a metal sleeve 20. This crimped heating conductor pair (21, 23) is situated on one peripheral side of the junction piece 11. The heating conductor 22 of one hose end (hose 14) is likewise crimped to the heating conductor 24 of the other hose end (hose 15) via a further metal sleeve 30. This crimped heating conductor pair (22, 24) is situated on the other peripheral side of the junction piece 11.
The crimped heating conductor pairs (21, 23) and (22, 24) are bent downward in a pressed together manner and, by way of the corresponding crimp sleeves (20, 30), are routed first from above beneath corresponding lateral bridge brackets (31, 32) of the housing 11 downward in the direction of the housing base 33. There, the heating conductor pair is deflected through 90° and placed around the base 33 of the junction piece 11 in close contact with the housing. The crimped heating conductor pairs (21, 23) and (22, 24) are then routed upward again on correspondingly opposite sides and, by way of the respective crimp sleeves (20, 30), are first passed from below through corresponding bridge bracket (31, 32), which form respective holding devices of the housing 11, and are therefore held at these locations.
The two bridge brackets (31, 32) are arranged opposite one another and bridge respective axial channels (34, 35). The axial channels are integrated in the surface of the cylindrical housing of the junction piece 11. The heating conductor pairs (21, 23) and (22, 24) are placed and therefore routed in these corresponding channels (34, 35), one arriving from above, and one arriving from the base 33.
In order to protect this assembled structure against external influences, the assembled junction piece 11 is then encapsulated with PUR or PA (FIG. 5). The potting layer 37 produced in this way covers the heating of the junction piece 11. The heating conductor sets (21, 22) and (23, 24) are insulated and protected.
It is understood that the foregoing description is that of the preferred embodiments of the invention and that various changes and modifications may be made thereto without departing from the spirit and scope of the invention as defined in the appended claims.
